Soybean Variety 5PKRH40 Breeding Program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and environmental tolerance, while existing methods are inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed to farmers.
Innovation Solution
The introduction of the novel soybean variety 5PKRH40, which includes methods for crossing, introgressing transgenic, mutant, or native traits, and characterizing the variety to produce stable, high-yielding soybeans with improved agronomic characteristics, disease resistance, and environmental tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves stability and high yield, but the development process takes six to twelve years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by establishing a comprehensive breeding program framework in advance, including predefined crossing schemes, selection criteria, and evaluation protocols. This structured approach allows the breeding process to proceed systematically without repeated directional changes, reducing the six to twelve year development timeline while maintaining variety stability through consistent selection pressure for desired traits
2Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves high yield and disease resistance, but resource efficiency is poor
Solution Approach 1:
The patent implements feedback mechanisms through systematic evaluation of breeding progeny against predefined performance targets for disease resistance and yield. This allows real-time assessment of selection effectiveness and adjustment of breeding strategies, improving resource efficiency by eliminating ineffective crossing combinations early in the process while maintaining reliable disease resistance through consistent selection criteria
3Adaptability or versatility
If traditional soybean breeding methods are used to achieve maximal yield over different conditions, then the variety shows environmental adaptability, but the breeding process lacks directional stability
Solution Approach 1:
The patent applies universality by designing a breeding program that simultaneously targets multiple desirable traits including yield, disease resistance, and environmental tolerance within a single integrated selection framework. This multi-functional approach ensures directional stability by maintaining consistent selection pressure across all traits throughout the breeding process, preventing drift while achieving comprehensive environmental adaptability
